[one-users] error monitoring host - even though logs indicate success

[Ruben S. Montero]

Hi,

No the host is not treated as in an error state. The ERROR message
(includind its TIMESTAMP) is left in the host template for information
purposes.

Once you have verified the issue you can freely remove the message doing

onehost update 1

Just remove the ERROR attribute in the editor.

Cheers

Ruben
